SIGNAL.

Specification of Letters Patent.

Patented Aug. 24, 1909.

Application filed February 6, 1909. Serial No. 476,370.

To all whom it may concern:

Be it known that we, JAMES M. KENNEDY and IRVIN W. GLnAsoN, citizens of the United States, residing at Lewisburg and Gleasonton, counties of Union and Clinton, respectively, and State of Pennsylvania, have invented a certain new and useful Improvement in Signals, of which the following is a specification.

Our invention relates to a new and useful improvement in signals, and has for its object to provide an exceedingly simple and effective device of this character whereby the engineer may be notified of impending danger.

A still further object of our invention is to provide a device of the character described which may be operated when the engine is moving backward as well as frontward.

It is a well known fact that when a storm is in progress it is generally impossible for the engineer of a train to see the signals beside the track or a fiagman who may have been sent out to flag the train, but by the use of our improved signal, which is carried by the engine, there may be a contact member which comes in contact with a portion thereof when the signal is set at danger, or there may be a detachable contact member which may be placed in position by a flagman, which will come in contact with a portion of the signal mechanism thereby blowing a whistle in the cab of the engine, thus notifying the engineer that he is to bring his train to a stop.

IVith these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, we will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in-

which Figure 1 is a longitudinal sectional View of our improved signal. Fig. 2, an end view thereof. Fig. 8, a side elevation of a detachable contact member, and Fig. 4, a section at the line wm of Fig. 3.

In carrying out our invention as here embodied, A represents a base member having openings B and 13 formed in the ends thereof and provided with a lug C, to which is pivoted the contact lever D, having the horizontal arms E and E, which are adapted to come in contact with the valve stems F and F of the valves G and Gr, which seat upon the valve seats H and H formed in the cylinders I and I, said cylinders being attached to the ends of the base member A.

The cylinders I and I are provided with covers J and J which are threaded on the tops thereof so that by removing said covers the valves may be removed and cleaned or newones put in their place.

K represents a supp y pipe leading from a supply tank, and from this supply pipe run branches K, which enter the cylinders I and I so that both of said cylinders will at all times be filled with air or steam as the case may be.

Leading from the openings B and B in the ends of the base member A are the pipes L and L, and the ends of these pipes are joined together, and leading from them to a whistle in the cab of the engine is a pipe \I.

M denotes a plate, to which are secured the cylinders I and I by means of the brackets M and this plate allows the mech anism to be fastened to some desirable part of the engine.

N represents a detachable contact mem her having a finger 0 formed with the base thereof, which is adapted to fit over the bottom flange of the rail, and to the base is slidably secured the member P, having the finger Q, which is also adapted to fit over the bottom flange of the rail, thus this contact member may be readily placed in position by a fiagman, and when an engine passes that point where it is attached, the contact lever D will hit against the contact member N thus blowing the whistle in the cab of the engine.

In practice the contact lever D'will abut the contact member N, at which time the contact lever D will be moved out of its vertical position causing one of the horizontal arms E or E to come in contact with its adjacent valve stem, thus opening the valve and allowing the air to pass from one of the cylinders through one of the openings B or B, then entering the pipe M through one of the pipes L or L, which will cause a signal to be turned on a whistle in the cab.

Of course we do not wish to be limited to the exact details of construction here shown as these may be varied within the JAMES M. KENNEDY, OF LEWISBURG, AND IRVIN W. GLEASON, 0F GLEASONTON, PENNSYLVANIA.

vided with a depending lug, cylinders provided with valve seats and having covers threaded on the tops thereof secured to the ends of the base member, valves provided with valve stems seating upon the valve seats in the cylinders, means attached to the depending lug of the base member for operating either of the valves, pipes leading from a supply tank to the cylinders and an other pipe leading from the openings in the ends of the base member to a whistle, as specified.

In combination, a base member having openings formed in the ends thereof provided with a depending lug, cylinders provided with valve seats and having covers threaded on the tops thereof secured to the ends of the base member, valves provided with valve stems seating upon the valve seats in the cylinders, a contact lever having horizontal arms formed therewith pivoted to the depending lug formed with the base member, said horizontal arms adapted to operate the valves when the contact lever is operated, a pipe leading from a supply tank, branches leading from said pipe to the cylinders, pipes leading from the openings in the ends of the base member, another pipe leading from the last named pipes to a whistle and means for securing said cylinders to an engine, as specified.

In combination, a base member having openings formed in the ends thereof provided with a depending lug, cylinders provided with valve seats and having covers threaded on the tops thereof secured to the ends of the base member, valves provided with valve stems seating upon the valve seats in the cylinders, a contact lever having horizontal arms formed therewith pivoted to the depending lug formed with the base member, said horizontal arms adapted to operate the valves when the contact lever is operated, a pipe leading from a supply tank, branches leading from said pipe to the cylinders, pipes leading from the openings in the ends of the base member, another pipe .with valve stems seating upon the valve seats in the cylinders, a contact lever having horizontal arms formed therewith pivoted to the depending lug formed with the base member, said horizontal arms adapted to operate the valves when the contact lever is operated, a pipe leading from a supply tank, branches leading from said pipe to the cylinders, pipes leading from the openings in the ends of the base member, another pipe leading from the last named pipes to a whistle, a plate, brackets for securing said plate to the cylinders, said plate adapted to be fastened to an engine and a detachable contact member for operating the contact lever, as shown and described.

5. In combination with a base member A having openings formed in the ends thereof and a depending lug of the cylinders I and I having valves therein, pipes leading from the openings in the ends of the base member A and a contact lever D having the horizontal. arms E and E pivoted. to the base member A, substantially as shown and described.

In testimony whereof, we have hereunto aflixed our signatures in the presence of two subscribing witnesses.
